Re: Converting grayscale png affects bit depth

Here is the updated png.c. All i did was flipped the ping_have_color default value from MagickTrue to MagickFalse. It fixes my problem with performance, and bit depth. Tested it in my workflows with different images. My patch is here: File: png.c line: 7969 ping_have_blob=MagickFalse; ping_have_chea...

Re: Help UnableToLoadModule IM_MOD_RL_JPEG_.dll

Hi if you are still having issues, run a dependency walker against your DLL, and see if you are missing additional dependencies.

Converting grayscale png affects bit depth

Hi, I have 2 test scenarios: First converting 16 bit Grayscale produces, 48 bit RGB. Second converting 8 bit Grayscale produces, 24 bit RGB. Tested using this image: 16 bit grayscale: http://cosmin.users.sourceforge.net/testing/lena_16g_lin.png 8 bit grayscale: http://upload.wikimedia.org/wikipedia/...

Re: Issue: Settings are not preserved

1. Ok thanks. -> But it seems that logic to disambiguate and "streamline/improve" setup could escape that. Since we have an option not to provide image.magick("ImageFormat"), and IM should figure out which format the image is auto-magically when writing it out to file with file extension.

It seems all those settings are gettin...

I have an image that i save with resolution and resolution unit like this: someImage.density(Geometry(resolution, resolution)); someImage.resolutionUnits(MagickCore::ResolutionType::PixelsPerCentimeterResolution); someImage.write(imagePa...

Re: Resolution units

@fmw42 i am setting density, and units, as in my original post. I debugged image magic, and the problem is during the retrieval of resolutionUnits from the image. After i read the image, i call to return resolution units In Image.cpp this code gets executed Magick::ResolutionType Magick::Image::reso...
